- Description: In this study I focus on a number of collections of short fiction by the South African writers Joël Matlou, Sindiwe Magona, Zoë Wicomb and Ivan Vladislavić, all of which evince certain of the characteristics of short story cycles or sequences. In other words, they display what Forrest L. Ingram describes as “a double tendency of asserting the individuality of [their] components on the one hand and of highlighting, on the other, the bonds of unity which make the many into a single whole”. The cycle form, thus defined, is characterised by a paradoxical yet productive and frequently unresolved tension between “the individuality of each of the stories and the necessities of the larger unit”, between “the one and the many”, and between cohesion and fragmentation. It is this “dynamic structure of connection and disconnection” which singularly equips the genre to represent the interrelationship of singular and collective identities, or the “coherent multiplicity of community”. Ingram, for example, asserts that “Numerous and varied connective strands draw the co-protagonists of any story cycle into a single community. … However this community may be achieved, it usually can be said to constitute the central character of a cycle”. Not unsurprisingly, then, in its dominant manifestations over much of the twentieth century the short story cycle demonstrated a marked inclination towards regionalism and the depiction of localised enclaves, and this tendency towards “place-based short story cycles” in which topographical unity is a conspicuous feature was as pronounced in South Africa as elsewhere. However, the specific collections which are my concern here increasingly employ innovative and self-reflexive narrative strategies that unsettle generic expectations and interrogate the notions of regionalism and community conventionally associated with the short story cycle. My investigation seeks to explain this shift in emphasis, and its particular significance within the South African context.

- Description: This novella presents three characters, each occupying a different sphere of reality. One is a ‘living dead’ who is forced to return to the land of the living for his continued existence. The other is a young woman who, having lost the will to live, must find a purpose if she is to continue living. The third is a young man who dwells more in the inner than the external world. Their lives intersect through the scripture known as ‘a fragment of a bone.’

- Description: This research focuses on the controversy surrounding the exhibition and media publication of Brett Murray’s painting, The Spear of the Nation (May 2012). It takes the form of a qualitative Critical Discourse Analysis (CDA), underpinned by Fairclough’s (1995) three-dimensional approach, to investigate how the contesting discourses articulated by the ruling political party (the ANC) and the news media have been negotiated in the City Press coverage in response to the painting. While the contestation was fought ostensibly on constitutional grounds, it arguably serves as an illustrative moment of the deeply ideological debate occurring in South Africa between the government and the national media industry regarding media diversity, transformation and democracy. It points to the lines of fracture in the broader political and social space. Informed by Foucault’s conceptualisation of discourse and the role of power in the production of knowledge and ‘truth’, this study aims to expose the discourses articulated and contested in order to make inferences about the various ‘truths’ the ANC and the media make of the democratic role of the press in a contemporary South Africa. The sample consists of five reports intended to represent the media’s responses and four articles that prominently articulate the ANC’s responses. The analysis, which draws on strategies from within critical linguists and media studies, is confined to these nine purposively sampled from the City Press online newspaper texts published between 13 May 2012 and 13 June 2012. Findings suggest the ANC legitimise expectations for the media to engage in a collaborative role in order to serve the ‘national interest’. Conversely, the media advocate for a monitorial press to justify serving the ‘public interest’. This research is envisioned to be valuable for both sets of stakeholders in developing richer understandings relevant to issues of any regulation to be debated. It forms part of a larger project on Media Policy and Democracy which seeks to contribute to media diversity and transformation, and to develop the quality of democracy in South Africa.

- Description: Background: In South Africa, limited research has focused on the task demands and workers responses associated with forestry silviculture work, particularly pitting and planting. The methods currently in use are manual, but despite our lack of understanding of the existing demands, advances in forestry engineering have resulted in an introduction of semi-mechanised versions of these tasks. This project aimed to compare the task demands of silviculture tasks using the current manual techniques and the more modern, semi-mechanised techniques. Methods: A holistic investigation focused on the worker characteristics of a sample of black male pitters and black female planters from the Kwa-Zulu Natal forestry industry, as well as biomechanical (spinal kinematics and L5/S1 forces), physiological (heart rate, oxygen consumption and energy expenditure) and psychophysical (ratings of perceived exertion and body discomfort) responses associated with manual and semi-mechanised pitting and planting. Results: The pitting task saw significant improvements in the spinal kinematic measures as a result of the increased mechanisation, with eight of the 16 recorded variables decreasing to a lower level of risk classification. Physiologically, the manual task was associated with a mean heart rate of 157 bt.min⁻¹ and absolute energy expenditure of 11.27 kcal.min⁻¹, which were not found to be significantly different to the values of 143 bt.min⁻¹ and 9.8 kcal.min⁻¹ recorded during the semi-mechanised technique. Psychophysical responses indicated that the workers perceived manual pitting to be more physically demanding than the semi-mechanised method. The manual and semi-mechanised planting tasks were, in general, found to be acceptable from a spinal kinematics perspective, with the majority of variables classified as low risk. However, the maximum sagittal angle was reduced by more than 20 degrees as a result of the new equipment. The physiological and psychophysical demands associated with manual planting were found to be within acceptable limits. Conclusion: In terms of pitting, it can tentatively be concluded that the semi-mechanised technique is better than the manual one, based on the biomechanical and psychophysical findings, however physiological demands require further investigation. When considering the planting techniques, the semi-mechanised method showed a slight improvement from the biomechanical perspective, but further physiological and psychophysical investigations are needed.

- Description: This study aimed to investigate the effects that a specifically tailored goal-setting program would have on two motocross racers in terms of their self-efficacy and motivation, as well as the process of designing this intervention. This case-study approach involved a mixed methods approach, consisting of pre-intervention and post-intervention assessments, interviews, and performance profiles. The tools used include Vealey’s (1986) Competitive Orientation Inventory (COI), Gill and Deeter’s (1988) Sport Orientation Questionnaire (SOQ), performance profiles, and semi-structured interviews. The goal-setting intervention lasted a total of five weeks. The results from the preintervention and post-intervention assessments were compared to determine whether any changes in motivation or self-efficacy occurred during the intervention. For the first participant, significant changes in both motivation and self-efficacy were present in addition to significant changes in competitive orientation. For the second participant, there were no significant changes in either motivation or self-efficacy. However, for the second participant there was also no change in competitive orientation. Findings suggest that the focus and competitive orientation of an athlete have a significant influence on the types of goals set, and consequently on positive changes in motivation, confidence, and self-efficacy. The influence of the competitive orientation in athletes also highlighted the importance of attaining a balance between performance and outcome goal-related activities. It was also discovered through qualitative assessment that this program is suitable for particular groups of athletes such as those who are injured, display an external locus of causality or are otherwise not performing at their prime.

- Description: This project asserts that revolution is characterised by the expression of unthinkable possibilities, and so addresses the paradox implicit in any attempt to "write revolution." That is, how does one represent revolution without reducing it to an ordered term of reference, and thereby subduing its radical character? Additionally, can transformative action be conceptualised as a creative project to which an ethical subject may, and in fact should, be drawn? To answer these questions, my investigation develops in three strands. I combine the radical theory of Alain Badiou with similar affirmations of revolutionary intervention from Slavoj Žižek and Paulo Freire, and so create an aesthetic that affirms revolutionaries as agents of supplementary creativity. My first purpose is thus to establish revolution as a productive enterprise that enables peace, rather than a destructive undertaking that introduces violence. This done, I apply the resultant conceptual tools to literary representations of radical transformation, and demonstrate that my aesthetic enables new readings of the literature of revolution to which it is applied. In the course of my analysis, I also evaluate the suitability of Badiou's ethic as a standpoint from which to engage with literature on revolution. Ultimately, then, the aesthetic I construct not only contests the notion that radical transformation is always destructive, but also renders one sensitive to revolutionary literature's excessive and supplementary dimensions.

- Description: Helen Martins devoted approximately the last thirty years of her life to converting her family home into a unique fantasy world which she named the Owl House. Since her death in 1976 the Owl House has become a national monument and museum in South Africa. Throughout her life Helen was considered by most of the surrounding villagers to have been strange, and she withdrew increasingly from society. However, she appeared to have contained a desire for human connection. There are several instances in which she expressed this desire, such as through the numerous letters which she wrote to fellow artists. The existing body of literature on Helen illustrates the complex nature of her personality; however the question of which personality style she best typifies has remained unanswered. In order to answer this question a psychobiography was conducted on Helen. Psychobiographies entail a biographical representation of a person's life history to which a psychological theory is applied. The psychological theory utilised within the current study was Millon's (1969/1996) Biosocial- Learning Theory. Thus, the chief objective of this study was to describe and interpret Helen's personality style through the use of Millon's (1969/1996) Biosocial-Learning Theory. Alexander's model of data extraction and Miles and Huberman's three step approach were implemented in order to reduce, organise and analyse the data. The findings of this study reflected that Helen deteriorated from one of Millon's (1969/1996) proposed personality styles to another as she aged. The current findings may illuminate Helen's motives for obsessively devoting her life to the creation of her fantasy world.

- Description: The net effect of pollen production on fecundity in plants can range from negative – when self-pollen interferes with fecundity due to incompatibility mechanisms, to positive – when pollen availability is associated with increased pollinator visitation and fecundity due to its utilization as a reward. We investigated the responses of bees to pollen and nectar rewards, and the effects of these rewards on pollen deposition and fecundity in the hermaphroditic succulent shrub Aloe tenuior. Self-pollinated plants failed to set fruit, but their ovules were regularly penetrated by self-pollen tubes, which uniformly failed to develop into seeds as expected from ovarian self-incompatibility (or strong early inbreeding depression). Bees consistently foraged for pollen during the morning and early afternoon, but switched to nectar in the late afternoon. As a consequence of this differential foraging, we were able to test the relative contribution to fecundity of pollen- versus nectar-collecting flower visitors. We exposed emasculated and intact flowers in either the morning or late afternoon to foraging bees and showed that emasculation reduced pollen deposition by insects in the morning, but had little effect in the afternoon. Despite the potential for self-pollination to result in ovule discounting due to late-acting self-sterility, fecundity was severely reduced in artificially emasculated plants. Although there were temporal fluctuations in reward preference, most bee visits were for pollen rewards. Therefore the benefit of providing pollen that is accessible to bee foragers outweighs any potential costs to fitness in terms of gender interference in this species.

- Description: Human wildlife conflict is a considerable conservation challenge that threatens many carnivore species worldwide and is a result of complex socio-economic and ecological processes. An understanding of the drivers of conflict is essential for any efforts to achieve coexistence. This study investigated the levels of conflict, livestock management and tolerance amongst the farming communities of the Southern and Western Kalahari in Botswana. A questionnaire survey was completed with 310 farmers throughout the region. The majority of respondents regarded coexisting with carnivores as a challenge, with losses due to depredation perceived as the greatest problem facing farmers. Conflict was widespread throughout the study area, with some spatial variations for certain species. Cattle management levels were low and while smallstock management was better, the use of improved levels of management could reduce current levels of conflict. Tolerance levels were generally low with few respondents seeing the benefits of coexistence with carnivore species. The results indicated that farm type, gender, education level, source of income, livestock numbers, location and land use all have an effect on perceived conflict and tolerance levels and strongly interact with each other. In general cattleposts were characterised by higher proportions of females, lower education levels, more benefits derived from wildlife and veld products and fewer livestock than fenced ranches. They also experienced more conflict, carried out more management and had better tolerance levels. It could be that closer connections to the land and deriving benefits from natural resources resulted in more tolerance and this is certainly worth further investigation. An improvement in the use of effective methods of livestock management, targeted environmental education programs to develop a greater awareness for the conservation value of carnivores and a diversification of livelihoods to include benefits from natural resources have the potential to reduce conflict and improve tolerance in the Kalahari region.

- Description: Freshwater resources are increasingly subject to pollution because of escalating human population growth, accompanied by urbanisation, industrialisation, and the increased demand for food. Consequently, freshwater quality, and aquatic ecosystem structure and function have been severely impaired. The Swartkops River, which drains an urbanised and industrialised catchment in the Eastern Cape of South Africa, is no exception. An integrated environmental water quality (EWQ) approach is needed to measure the impacts of deteriorating water quality on its aquatic ecosystem structure and function to sustain these vital ecosystem-attributes. In this study, an integrated EWQ approach, which included i) analysis of water physico-chemical variables; ii) macroinvertebrate-based family-level taxonomic- and traits-based community analysis; iii) Chironomidae species-level taxonomic- and traits-based community analysis; iv) Chironomidae deformity-based sub-lethal analysis; and v) experimental investigation of long-term wastewater effluent effects, using model stream ecosystems, were applied to investigate environmental water quality in the Swartkops River. One upstream reference site and three downstream sites in the Swartkops River were monitored over a period of three years (August 2009 – September 2012). The family-level taxonomic community responses based on the South African Scoring System version 5 (SASS5) and a newly developed Swartkops multimetric index indicated very poor river health conditions for the three downstream sites, compared with the good condition of the upstream site. The Chironomidae species-level responses in the three downstream sites provided evidence of differences in biotic impairments, which were not evident with the family-level taxonomic data at these sites, thus highlighting the importance of species identification in freshwater biomonitoring. The family-level traits-based approach (TBA) showed that macroinvertebrates with gills and lungs were more abundant at the upstream site, decreasing markedly at the downstream sites. The relative abundance of macroinvertebrates relying on aerial and tegument respiration increased at the downstream sites compared with the upstream sites. The results of the family-level TBA highlighted the inextricable link between the traits-based approach (TBA) and taxonomic identification, clearly showing that the TBA is additional to, and not an alternative to, taxonomic recognition because important traits, e.g. reproductive cannot be used at a coarse taxonomic identification. A novel chironomid species traits-based functional strategies approach developed in this study, based on species combining similar sets of traits, proved sensitive in diagnosing the main abiotic water physico-chemical stressors. The functional traits responded predictably to deteriorating water quality and provided an adaptive and mechanistic basis for interpreting chironomid species occurrences at the four sampling sites, providing insight into why certain chironomid species occurred at one site but not at the other. Chironomid deformities provided evidence of sub-lethal in-stream biological response to deteriorating water quality. A newly developed deformity-based extended toxic score index proved sensitive, enabling the discrimination of the sampling sites, indicating that a biomonitoring tool based on sub-lethal effects could be used to assess the effects of deteriorating water quality before it reached lethal levels. Empirical evidence based on the taxonomic, traits and sub-lethal responses suggested that the changes in macroinvertebrate community structure were caused chiefly by the discharge of wastewater effluents into the river. This was supported by the model-stream ecosystem results indicating significant effects of effluents on the macroinvertebrate community structure, similar to the observed in-stream responses. The model stream results indicated that improved physico-chemical effluent quality compliance after 50% effluent dilution did not significantly reduce the effects of the effluent on the macroinvertebrate communities, showing that ecologically-based methods rather than physico-chemical measures alone are necessary to assess effluent quality. Finally, the results of the multi-criteria approach were integrated to propose tools to manage environmental water quality in the Swartkops River, and the benefits of the study were highlighted in the context of biomonitoring in South Africa.

- Description: Environmental challenges facing the world currently call for efforts that can avert eminent disasters related to these challenges. In an effort to engage in conservation, the Environmental Resource Management course at Technical University offers an opportunity to train for sustainable development in the country. However, the development and implementation of courses aimed at developing careers in sustainability in institutions of higher learning are coming under scrutiny as questions are being asked about their contributions to sustainable development. This research explored the Environmental Resource Management course to understand how it was developed and implemented to address a practitioner in the environmental resources conservation sector. The study surfaced the contradictions in the course which can be used as a lens to re-orient the course to enable a practitioner in education for sustainable development to emerge. In Kenya, vocational courses in environmental education are a career choice for secondary school leavers and those engaged in the environmental conservation sector. This study carried out at Technical University of Kenya (TU-K) between January 2009 and April 2012 aimed at exploring how a diploma course: Environmental Resource Management (ERM) enabled the learners to become practitioners in environmental resource management. It surfaced contradictions and suggested transformative approaches to re-orient the course for sustainable development. This was necessitated by the paradigm shift in environmental education from environmental conservation education that emphasised ecological studies to Education for Sustainable Development that is broader and more holistic, encompassing social, economic and environmental aspects. The course has to be re-orientated to enable a practitioner in Education for Sustainable Development (ESD) to emerge considering the United Nations Decade of Education for Sustainable Development (UNDESD, 2005-2014). The course aims at training personnel for deployment in environmental conservation and management organisations to work as resource officers/supervisors in national parks, forestry management, water management, energy development projects officers, etc. Data was gathered through document analysis, questionnaires, interviews, observation and focus group discussions. Cultural Historical Activity Theory (CHAT) was engaged in surfacing contradictions in the Environmental Resource Management learning system in terms of its development and implementation. While Communities of Practice (COP) principles were used as the ontological underpinning for the ERM course. The results indicate that the ERM course was revised between 1998 and 2002 by experts from Saskatchewan Institute of Science and Technology (SIAST) in collaboration with TU-K staff under the programme, enhancing environmental management in Kenya. The research also established that the ERM course review process was informed by sustainable development principles, as outlined in Agenda 21. Further it was realised that the Develop a Curriculum (DACUM) process was engaged to develop the learning units. This course development envisaged Competency Based Education (CBE) as the main mode of the ERM delivery. CBE is student centred and allows for multi-entry and exit. The study however realised that at implementation this approach was partially incorporated, as the country’s education system is examination oriented and time bound. The study findings indicate that most of the units taught were on ecosystem management with the social and economic aspects having less space and time, therefore the three pillars of Education for Sustainable Development were not adequately addressed in the course to enable a practitioner in the concept to emerge. Also teaching and learning in the course was found to be more theoretical than practical with little hands-on activities because the main focus of the course was to enable the learners to acquire a certificate through examination rather than gain the appropriate competencies. Although the course was found to be enhancing ESD in relation to global and local sustainability issues, there were contradictions or challenges in the system that affected full realisation of the skills, knowledge, values and attitudes. For example the exclusion of the recipient staff in the planning of the course, lack of training of the lecturers on how to train on CBE, insufficient practical field excursions devoid of community engagement, lack of funds, lack of equipment and poor coordination. This study recommends a re-orientation of the course to a more practical approach to teaching such as: • Engagement of students with the community to solve real-life environmental problems; • Mainstreaming ESD in all courses in the institutions of higher learning so that environmental concerns are addressed by everyone; • Reviewing the educational policy to encourage solving of real-life environmental problems rather than passing theoretical examinations; • Enhancing competency based learning to enable students to become competent in their areas of specialisation; • Encouraging networking and direct involvement of the students in the community instead of spending more time in class; and • Establishing a Community of Practice among the students in Higher Education Institutions to enhance conservation practices. The study contributes in-depth insight into exploring courses in Technical Vocational Education and Training institutions using Communities of Practice as a lens within the Kenyan context. It gives some empirical and explanatory insight into how learning can emerge and be expanded in Education for Sustainable Development through relevant courses such as tje Environmental Resource Management course. It also provides learning tools to work with contradictions that arise from socio-cultural and historical dimensions of learning about natural resources in the Kenyan context. Its other key contribution is that it provides further insight into the re-orientation of the ERM courses to embrace ESD for a broader and a more holistic approach to natural resources conservation and poverty alleviation processes that are critical for responding to socio-ecological issues and risks and development challenges in Kenya.

- Description: This qualitative case study was undertaken in order to explore the experiences of drum set students who apply themselves to James Dreier’s Standard Tune Learning Sequence (STLS) in a self-directed learning environment. These experiences ultimately shed light on how best to implement Differentiated Instruction to the STLS. The study draws on the experience of three adult drum students under the instruction of the author. The students were provided with the STLS and left to proceed with it on their own. They were asked to keep a record of their progress in the form of a learning journal. These learning journals were used, in conjunction with transcribed interviews and learner profiles, as data for this study and as such were subjected to Interpretative Phenomenological Analysis. The study recognizes three factors which affect the student’s successful progression through the STLS: readiness, interest and meaning. Each factor is discussed in relation to literature on differentiated Instruction. Recommendations are made regarding the implementation of Differentiated Instruction to the STLS.

- Description: This qualitative study, focussing on the way in which values and valuing processes might strengthen social learning in water stewardship practices in South Africa, is located within the broader global narrative that describes the scale of human impact on our Earth systems and that is setting humanity on a trajectory that threatens to place us beyond the safe operating spaces called planetary boundaries. For humanity to live within planetary boundaries – one of which is global freshwater use –will take a new way of relating to the environment called Earth stewardship, which calls for a new ethic of responsibility towards Earth systems. It is at the local level of stewardship within a global approach to water resources management called integrated water resources management that this qualitative study is contextually bound. Two case studies, located in the catchment management forums (CMFs) of the Upper Vaal catchment of Gauteng, South Africa, are used in an exploration of the way in which values and valuing processes might strengthen social learning in water stewardship practices in South Africa. The meta-theory of critical realism is used to help explore this relationship between values, practice and social learning. The study uses document analysis, interviews and observation of selected water stewardship practices to identify held and assigned values, and valuing processes and their influence on social learning, and the framing and de-framing processes that occur in social learning oriented towards water stewardship practices. The study differentiates between held and assigned values and identifies a strong altruistic-held values tendency that characterises forum participants who practice water stewardship in the two case study sites. Most water stewardship practice, identified in the case study sites, manifests as compliance activities in the public – or forum – space, while private-sphere environmentalism is mostly left to the confines of the individual’s private household. Lastly, the CMFs seem to have the potential to provide a space for social learning that is not yet maximised. Drawing from these key findings, the study’s major recommendation is that forums that facilitate learning, either using the current CMF structure or creating new opportunities, need to be provided as a conduit for social learning and reflexivity to make the existing boundaries between private and public forms of water stewardship more porous. This social learning may expand social practice and thus strengthen social change processes that expand water stewardship practices.

- Description: This thesis reports on a multiple case study PhD project that aimed to investigate meaningful and critical development of knowledge and strategies to teach visual literacy, a component of English First Additional Language (FAL) in six under-resourced schools of the Eastern Cape of South Africa. The study begins by locating visual literacy within a broad framework of literacy as a social practice, and discusses its importance. Further, it discusses complexities of making sense of and teaching visual literacy, especially for the majority of in-service teachers who experienced visual literacy neither as learners nor as teacher trainees. The gap between the curriculum and teachers’ classroom practices is what triggered this study to adopt a transformative paradigm. The main research question is, “How can teacher professional development in English Language Teaching advance in-service teachers’ knowledge of and strategies for meaningful and critical teaching and learning of visual literacy?” To respond to this question, I drew on cultural historical activity theory (CHAT) and critical realism (CR) to design four phases of this study that incorporated the seven stages of an expansive learning cycle. These phases focussed on exploring and expanding teachers’ sense making and teaching of visual literacy. I collected data through interviews, document analysis, videoed lessons and change laboratory (CL) workshops. I designed a data analysis tool that brought together CHAT, CR, multimodal social semiotics, critical discourse analysis and pedagogical discourse to make sense of the data. Through a process of reflexivity, the study illuminated layers of factors that constrained meaningful and critical teaching of visual literacy in the empirical, the actual and the real domains of reality. These factors include teachers’ unconscious reproduction of discourses of domination, their intolerance of diverse cultural discourses, resistance to curriculum change, and the fact that they are comfortable with the status quo. I brought these factors to CL workshops for expansive learning. The study contributes in-depth insight into English FAL in-service teacher development in the area of visual literacy. By locating the study within meaning making and teaching of visual literacy, it was possible to interrogate access, diversity, domination and design in teachers’ classroom practices. As a result of this study participants were made aware of the extent to which these factors enabled or hindered meaningful and critical teaching. Participants repositioned themselves as subjects of the activity system, thereby mobilising their agency to take control of the structures and cultures that condition their teaching.

- Description: Leopards (Panthera pardus) are the most common large predators, free roaming outside of protected areas across most of South Africa. Leopard persistence is attributed to their tolerance of rugged terrain that is subject to less development pressure, as well as their cryptic behaviour. Nevertheless, existing leopard populations are threatened indirectly by ongoing transformation of natural habitat and directly through hunting and conflict with livestock farmers. Together these threats may further isolate leopards to fragmented areas of core natural habitat. I studied leopard habitat preferences, population density, diet and the attitudes of landowners towards leopards in the Little Karoo, Western Cape, South Africa, an area of mixed land-use that contains elements of three overlapping global biodiversity hotspots. Data were gathered between 2010 and 2012 using camera traps set up at 141 sites over an area of ~3100km², GPS tracking collars fitted to three male leopards, scat samples (n=76), interviews with landowners (n=53) analysed in combination with geographical information system (GIS) layers. My results reveal that leopards preferred rugged, mountainous terrain of intermediate elevation, avoiding low-lying, open areas where human disturbance was generally greater. Despite relatively un-fragmented habitat within my study area, the leopard population density (0.75 leopards/100km²) was one of the lowest yet recorded in South Africa. This may reflect low prey densities in mountain refuges in addition to historical human persecution in the area. Currently local landowners are more tolerant of leopards than other wildlife species with incidents of conflict involving leopards being rare relative to black-backed jackals (Canis mesomelas), baboons (Papio hamadryas), caracals (Caracal caracal) and porcupine (Hystrix africaeaustralis). Although current levels of conflict between leopards and stock farmers are low, leopards do depredate livestock, which constitute 10-15% of their diet. Improved livestock husbandry measures and co-operation between conservation authorities and farmers are necessary to mitigate such conflict and balance economic security with biodiversity conservation in the region. Leopards are the only remaining top predators throughout much of the Little Karoo and the Western Cape and as such are predicted to play a critical role in ecosystem structure and the survival of other species. Current high levels of connectivity between areas of suitable leopard habitat bode well for the conservation status of leopards within this region and future conservation efforts need to ensure that narrow corridors linking such habitat are preserved. The potential for leopards to serve as both an umbrella and a flagship species for biodiversity conservation suggests that long term monitoring of this population would be a conservation priority for the Little Karoo.

- Description: The catface rockcod Epinephelus andersoni is a range-restricted species that is endemic to the southeast coast of Africa from Quissico in Mozambique (subtropical) to Knysna in South Africa (warmtemperate). Its complex life-history, long-lived nature and high residency make E. andersoni potentially vulnerable to over-exploitation. Epinephelus andersoni is an important fishery species and has shown signs of depletion. Due to inadequate information necessary for management and conservation, further research is vital, particularly in the face of potentially significant climatic changes which could put further pressure on E. andersoni. The aim of the study was to provide information for the management of E. andersoni, with considerations for the possibly detrimental effects of future climate change. The objectives of this study were to describe the genetic structure and diversity of E. andersoni and to determine possible range shifts of E. andersoni with future changes in sea surface temperature. Genetic samples were collected throughout the distribution of E. andersoni. Standard DNA extraction and PCR using universal primers were conducted and nuclear (RPS7-1) and mitochondrial (cytochrome b) data were analysed to determine genetic diversity. A combination of nuclear and mitochondrial markers was used to ensure that the results were robust. RPS7-1 haplotype diversity was high (0.801) and an AMOVA on the RPS7-1 data showed significantly high among group variation (ΦCT = 0.204, p < 0.05) between five groups: 1. Quissico to Inhaca; 2. Cape Vidal to Port Edward; 3 Port St Johns to Coffee Bay; 4. Mbashe; 5. Port Alfred. This geographic structuring could be attributed to low gene flow across barriers such as the Port Alfred upwelling cell, the Mozambique Channel eddies and smaller more localised upwelling cells such as the Port St Johns cell. The cytochrome b results contrastingly indicate low haplotype diversity (0.309) and no differentiation (ΦCT = 0.265, p = 0.074) between groups and support the hypothesis of a historical population bottleneck. This may be due to an unusually slower mutation rate of the cytochrome b region than the RPS7-1 region, resulting in the RPS7-1 data showing a more recent picture of diversification. To complement the genetic results, niche modelling techniques were used to determine range shifts of E. andersoni with future temperature trends using species distribution and climatic data. The model illustrated a contraction of the E. andersoni distribution as well as future intensification of various upwelling cells along the south-east African coast including the Port Alfred upwelling cell. Due to the low gene flow across these barriers this intensification could decrease the resilience of E. andersoni, as its range becomes more limited with global change. The genetic data and modelling results combined provide useful information on which to base future fisheries management.

- Description: Aquatic weeds transform and degrade the ecosystems which they invade, impacting various aspects of their surroundings ranging from the community level to disrupting important processes affecting ecosystem services. All of the major aquatic weeds of South Africa are found in the Cape Town Metropolitan Area. Landowners, whether private or public, are legally obliged to manage the listed invasive species through applying environmentally acceptable methodologies. This thesis provides an overview of the strategic management options, prevention, early detection, rapid response and eradication of new invasions, and containment and control species of established species. It discusses the different control methods available for managing aquatic weeds, namely mechanical, manual, chemical and biological, and the integration of different methods to improve their effectiveness. Although various studies have shown that biological control is the most cost–effective, environmentally-friendly and sustainable method, it is not yet fully integrated into weed management programmes in South Africa. In addition, the successes achieved in other parts of the world with the control of water hyacinth through biological control have not been repeated in the urban environment, despite the fact that South Africa has the highest number of biological control agents available for the weed. Urbanisation puts pressure on the natural environment and ecosystem functioning. Nutrient-enriched waters support aquatic weed growth and pose a challenge to the management thereof, in particular with regard to integrating biological control into management programmes. The aims of this study were to determine the reasons for the lack of integration of biological control into weed management programmes in South Africa, to determine the feasibility of integrating biological control in aquatic weed management programmes in a complex urban environmental and socio-political landscape by means of three case studies in the Cape Town Metropolitan Area, which showed that biological control is feasible in urban environments and should be considered. Two surveys were conducted to determine the reasons for the lack of integration of biological control into weed management programmes. The surveys showed that there is a gap between research and implementation as a result of poor communication, non-supporting institutional arrangements and a lack of appropriate capacity and skills at the implementation level. Recommendations were offered to address these issues.

- Description: The central argument of this thesis asserts that in the process of challenging dominant subject positions, such as whiteness, performance creates the possibilities for new or alternative arrangements of desire. It examines how the creative process of desire is forestalled (reified) by habitual representations of whiteness as a privileged position, and proposes that performance can be a valid form of resistance to static conceptions of race and subjectivity. The discussion takes into account how the privilege of whiteness finds representation through forms of neo-liberalism and neo-colonialism in the post apartheid context. The analysis focuses on the work of white South African artists whose work offers a critique from within the privileged “centre” of whiteness. The research is situated within the inter-disciplinary field of performance studies entailing a reading and application of critical texts to the analysis. Alongside this qualitative methodology surfaces a subjective dialogue with the information presented on whiteness. Part Two includes an analysis of Steven Cohen’s The Cradle of Humankind (2011), Brett Bailey’s Exhibit A (2011) and Michael MacGarry’s LHR-JNB (2010). Each section examines the way in which the respective works engage in a questioning of whiteness through performance. Part Three investigates South African rap-rave duo, Die Antwoord and how their appropriation of Zef interrogates desires for an essential authenticity. Part Four focuses on my own performance practice and the proposed value of engaging with a form of practice-led research. This is particularly relevant in relation to critical race studies that require a level of self-reflexivity from the researcher. It presents an analysis of the work entitled Villain (2012) as a disturbance of theatrical desire through a process of ‘becoming’. This notion of meaning and identity as ‘becoming’ is argued as a strategy to challenge prevailing modes of perception which can possibly restore the production of desire to the viewer. The thesis concludes with the notion that performance can offer a mode of immanent ethics which is significant in creating both vulnerable and critical forms of whiteness.

- Description: In recent years higher education institutions have come under increasing financial pressure. This has not only prompted universities to investigate more cost effective means of delivering course content and maintaining research output, but also to investigate the administrative functions that accompany them. As such, many South African universities have either adopted or are in the process of adopting some form of cloud computing given the recent drop in bandwidth costs. However, this adoption process has raised concerns about the security of cloud-based information and this has, in some cases, had a negative impact on the adoption process. In an effort to study these concerns many researchers have employed a positivist approach with little, if any, focus on the operational context of these universities. Moreover, there has been very little research, specifically within the South African context. This study addresses some of these concerns by investigating the threats and security incident response life cycle within a higher education cloud. This was done by initially conducting a small scale survey and a detailed thematic analysis of twelve interviews from three South African universities. The identified themes and their corresponding analyses and interpretation contribute on both a practical and theoretical level with the practical contributions relating to a set of security driven criteria for selecting cloud providers as well as recommendations for universities who have or are in the process of adopting cloud computing. Theoretically several conceptual frameworks are offered allowing the researcher to convey his understanding of how the aforementioned practical concepts relate to each other as well as the concepts that constitute the research questions of this study.

Combating corruption while respecting human rights : a critical study of the non-conviction based assets recovery mechanism in Kenya and South Africa

- Description: The thesis contributes to the search for sound anti-corruption laws and practices that are effective and fair. It argues for the respect for human rights in the crafting and implementation of anti-corruption laws as a requisite for successful control of corruption. The basis for this argument is threefold: First, human rights provide a framework for checking against abuse of state’s police power, an abuse which if allowed to take root, would make the fight against corruption lose its legitimacy in the eye of the people. Second, human rights ensure that the interest of individuals is catered for in the crafting of anti-corruption laws and practices thereby denying perpetrators of corruption legal excuses that can be exploited to delay or frustrate corruption cases in the courts of law. Third, human rights provide a useful framework for balancing competing interests in the area of corruption control – it enables society to craft measures that fulfils the public interest in the eradication of corruption while concomitantly assuring the competing public interest in the protection of individual members’ liberties – a condition that is necessary if the support of the holders of these competing interests is to be enlisted and fostered in the fight against corruption. The thesis focuses on the study of the non-conviction based assets recovery mechanism, a mechanism that allows the state to apply a procedure lacking in criminal law safeguards to address criminal behaviour. The mechanism is thus beset with avenues for abuse, which if unchecked could have debilitating effects not only to individual liberties but also to the long term legitimacy of the fight against corruption. In this regard, the thesis examines how the human rights framework has been used in Kenya and South Africa to check on the potential dangers of the non-conviction based mechanism and to provide for a proportional balance between the imperative of corruption control and the guarantee against arbitrary deprivation of property. The aim is to unravel the benefits of respecting human rights in the fight against corruption in general and in the non-conviction based assets recovery in particular. Kenya and South Africa are chosen for study because they provide two models of non-conviction based mechanisms with different levels of safeguards, for comparative consideration.
